UT699 ABI CFLAGS Question

[Daniel Hellstrom]

Hi Joel,

The UT699 uses --mcpu=leon because it has a matching ISA. The mcpu=leon3 
generates CAS instruction which is not present in UT699. With 
--mcpu=leon is used with --mfix-ut699 there are some UT699 specifics 
enabled. I think the yml-file looks correct.
